PSET(nged)

set a scalar parameter of a primitive

💅 PSET 💅

ok so this is the pset page from the nged manual — BRL-CAD user commands, bestie, we're in mged territory 🫶

✨ NAME ✨

pset — set a scalar parameter of a primitive. that's it, that's the whole vibe 💖

🌸 SYNOPSIS 🌸

pset obj attribute val

🦋 DESCRIPTION 🦋

ok so picture this: the pset command sets a scalar parameter of the BRL-CAD primitive obj to whatever value you hand it in val. you pick which parameter using a single-letter attribute code (yes, literally one letter, iykyk 👑). then the modified object gets written back to the database. slay, it persists. ✨

the val argument has to be a single floating-point number — one number, that's the whole assignment, no funny business 😭. path prefixes on obj are totally fine (like comb/part.s); it's the trailing component name that gets used for the lookup. so go ahead and be specific, it's giving main character energy 🌈

lowkey important: currently only METABALL primitives are supported. any other primitive type just returns an error. no cap, that's the rule 💀

🎀 METABALL attributes 🎀

here's the tea on the attribute codes for METABALLs, bestie 🍓

  • m or M — Render method! the valid values are 0 (Metaball), 1 (iso-surface), and 2 (Blob). values below 0 get clamped to 0, and values above 2 get clamped to 2 — so you literally cannot escape the range, it's giving strict parents 💅
  • t or T — Threshold value! this sets the field threshold used during metaball rendering. and here's the cute part: if you give it a negative value, its absolute value is used. so -1.5 becomes 1.5, math said no negativity today ✨

🔥 EXAMPLES 🔥

Example 1. Set the render method of a metaball

mged> pset blob.s m 2

Sets the render method of the metaball primitive blob.s to Blob mode (method 2). iconic. 👑

Example 2. Set the threshold of a metaball

mged> pset cloud.s t 1.5

Sets the field threshold of the metaball primitive cloud.s to 1.5. see how clean that is 😌
